The Geospatial Data Abstraction Library (GDAL) is a unifying
C/C++ API for accessing raster geospatial data, and currently
includes formats like GeoTIFF, Erdas Imagine, Arc/Info
Binary, CEOS, DTED, GXF, and SDTS. It is intended to provide
efficient access, suitable for use in viewer applications,
and also attempts to preserve coordinate systems and metadata.
Python, C, and C++ interfaces are available.
